Filed: 1988-11-10
Granted: 1990-12-18
Abstract: ABSTRACT OF THE DISCLOSURE     A round haybale unloader is disclosed for transporting and unwinding cylindrical bales of hay, straw or like fibrous agricultural material.  The invention provides a relatively compact, self-powered and self-propelling unloader for unrolling a continuous sheet of agricultural material from a cylindrical bale.  The haybale unloader allows for convenient transport of bales and is easily operated by a single person.  In a preferred embodiment, the unloader comprises a wheeled frame on which are disposed a support surface for a bale and a conveyor having a forward discharge end and rearward receiving end. The support surface and conveyor are upwardly inclined in the direction of discharge.  A sloped limiting surface is disposed adjacent the receiving end of the conveyor and extends upwardly therefrom in an obtuse angle relationship thereto.  A laterally spaced apart pair of freely pivoting bale retaining arms is provided for rotatably retaining the bale against the support surface and limiting surface.  A clamping disk and spear assembly is disposed at each free terminal end of the retaining arms and is adapted for slidable and rotatable interconnection therewith and for engagement with the respective end surfaces of a bale near its central longitudinal axis.  The conveyor unrolls a bale placed onto the support surface by imparting a rotative movement to the bale about its central longitudinal axis and drawing therefrom a continuous sheet of agricultural material for distribution along the ground adjacent the discharge end of the conveyor.  The limiting surface arrests the rearward motion of the bale and the bale retaining arms stabilize the rotative movement of the bale throughout the unrolling thereof.  A winch and retractable loading ramp may be provided for loading the bale onto the support surface.  The unloader also comprises a steering mechanism and a drive source for actuating the conveyor, winch and rear wheels of the frame.

Abstract: ABSTRACT A process and material is disclosed for use in the manufacture of a tensioned mask color cathode ray tube which includes a faceplate having on its inner surface a phosphor screen, and having on opposed sides of the screen a support structure for the mask.  The process comprises providing an apertured foil shadow mask characterized by being composed of a nickel-iron alloy, and securing the foil mask to the support structure while under tension and in registration with the phosphor screen.  The process is further characterized by the subjection of the foil mask to a thermal cycle to partially anneal the mask to a state in which the mask has favorable magnetic and mechanical properties.  The partial anneal may be accomplished as a discrete step prior to installing the mask on the support structure, or accomplished during, or as a result of, a thermal cycle in the process of sealing the tube.  The material comprises a nickel-iron alloy that displays, following treatment according to the invention, characteristics that make it uniquely suited for use as a shadow mask in tensioned mask color cathode ray tubes.

Abstract: A .beta.-galactosidase complementation assay for determining the presence of an analyte which is a member of a specific binding pair (sbp) in a sample is provided, which assay permits visual discrimination between those samples wherein the analyte is present above a predetermined, threshold concentration.  The method comprises combining the sample with a hydro-phobic enzyme donor- (ED-) analyte conjugate and the                   x complementary member of the sbp to form an sbp complex-containing assay medium.  A small volume of the assay medium is spotted onto an enzyme acceptor (EA) affixed to a bibulous, solid support, followed by development with enzyme substrate solution.  A substantially larger area is detectable when analyte in the sample is below as compared to above a threshold concentration.  The assay is particularly useful in field testing applications such as determining the presence of antibiotics in milk, toxins in water, or drugs in serum or urine.  Kits facilitating the method are also provided.
